Change broadcast code

[jenamax]

Hello! As I understand from the description to launch the lidar driver need to use the broadcast code which is individual for each sensor (not IP address like int the livox_ros_driver2). But it is very inconvenient as I cannot use the same code for all lidars, it requires to modify the config every time. Is it possible to change the broadcast code so that I could configure the lidar and then launch the same code?
